[PA-1-17] Retrospective Study of Robotic approaches for rehabilitation of hand function after stroke
Objectives. The purpose of this study was to investigate the effects of using a hand training robot on hand function in stroke patients before and after the intervention, and the differences in progression of different initial hand abilities.
Methods. Data were obtained by retracing the medical records of 14 patients using the Amadeo robotic system (Tyromotion GmbH Graz, Austria)(hereafter referred to as Amadeo). Outcomes included results from the following assessment tools: Fugl-Meyer Assessment-motor (FMA-motor), Box and Block Test (BBT), and assessments built into the Amadeo, including range of motion, and muscle strength. Paired t-tests were used to analyze the effects before and after the intervention. Analysis of Variance (ANOVA) was used to analyze the differences in progress between patients with different Brunnstrom stage.
Results. After Amadeo hand functions intervention in stroke patients, there were significant differences (p<0.05) in all scales before and after treatment, except for the thumb flexion range of motion and hand extension strength. Patients in the Bruunstrom stage V had significantly higher BBT assessment scores than the other three groups; the Fugl-Meyer scale, hand strength and range of motion were not significantly correlated with each Bruunstrom stage.
Conclusion. Stroke patients showed improvements in range of motion, strength and hand function after receiving the Amadeo intervention. These improvements were particularly evident in patients with better hand function prior to treatment. The results of this study can provide a reference for clinical occupational therapists who use Amadeo as a hand movement training, in terms of hand function outcome expectations.
